The dog, also known as the domestic dog (lat. Canis lupus familiaris), is a domesticated mammal (Mammalia) from the dog family (Canidae). Archaeological findings prove that the dog has lived with humans for at least 9,000 years, although there are indications that this period will be extended to as much as 14,000 years. Fossil remains show that the ancestors of the modern dog lived with man 10,000 years ago. Today, there are about 40 million dogs and about 800 breeds (which is more than any other species of animal) of various dimensions, physiognomy and temperament, and which represent the most diverse varieties of color and type of hair. The dog is closely connected with man, whom he serves as a pet, as a guard, guide, shepherd, etc. The dog is one of the most widespread animals in the world, whose popularity is surpassed only by the cat (Felis catus). The dog is a subspecies of the gray wolf (Canis lupus), which is believed to be the direct ancestor of the dog. Recent research confirms that the dog was first domesticated in East Asia, most likely in China. Also, it is not certain that all domestic dogs come from the same group or that the domestication process is repeated several times in several places.
